Signaling methods for reducing power consumption of wireless devices
Methods, systems, and devices for signaling to reduce power consumption of wireless devices are described. An example method for wireless communication includes transmitting, by a network node to a wireless device in communication with the network node, a control information that is based on the wireless device being in a power-normal state or not being configured to operate in a power-saving state. Another example method for wireless communication includes receiving, by a wireless device from a network node, a control information that is based on the wireless device being in a power-normal state or not being configured to operate in a power-saving state.
